All protocol droids use normal minifigure body and leg shaped pieces. All protocol droids share the same head piece as C-3PO, although they are coloured differently, (excluding 4-LOM (Video Game only) and the RA-7 Protocol Droid).
List of Protocol Droids
- TC-14 is often mistaken for an Episode II (Attack of the Clones) variant of C-3PO because of her silver plating.
- TC-4 is often mistaken for R-3PO for the color they share.
- O-MR1 and W1-LE are videogame exclusive characters. 4-LOM was originally videogame only, but a new set is being released that includes him.
- The Imperial Protocol Droid, or "Death Star Droid" is actually a RA-7 series protocol droid, but he has the same head mold as the 3PO droids and TC droids. The light grey protocol droid that came in 75051 Jedi Scout Fighter was the first droid to have the correct head mold, followed by The Death Star Droid from the newer Death Star set, and then O-MR1.
